ASP0113 groupExperimentalParticipants receive 1 mL of ASP0113 intramuscularly 5 times, on days -14 to -3, 14 to 40, 60 ± 5, 90 ± 10, and 180 ± 10, counting from the transplantation (stem cell transfusion) day (day 0)
Receives: Biological: ASP0113

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Safety assessed by the incidence of adverse events, vital signs, physical exam and labo-tests

    Measured: for 365 days after HCT

Secondary outcomes (5)
  1. Local reactogenicity

    protocol-specified reactogenicity scale

    Measured: for 14 days following each injection

  2. Incidence of CMV viremia

    CMV plasma viral load ≥ 1000 copies

    Measured: for 365 days after HCT

  3. CMV-specified antiviral therapy

    CMV-specific AVT(Anti-virus therapy) initiated for a CMV plasma viral load ≥ 1000 copies

    Measured: for 365 days after HCT

  4. Incidence of cytomegalovirus end-organ disease (CMV EOD)

    CMV pneumonia, CMV gastroenteritis, CMV hepatitis, et al

    Measured: for 365 days after HCT

  5. Maximum grade of Graft Versus Host Disease (GVHD)

    Measured: for 365 days after HCT

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing ASP0113 in people with Allogeneic Hematopoietic Cell Transplant, run by Astellas Pharma Inc at 2 sites in Japan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 17 Oct 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Japan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Safety assessed by the incidence of adverse events, vital signs, physical exam and labo-tests (time frame: for 365 days after HCT). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01903928, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Oct 2024.
